SHENYANG, Feb. 11  -- A company based in northeast China's Shenyang City has begun to supply components for the tail part of Boeing's 777 line of airplanes.

Boeing has received the first shipment of forward torque box panels from the AVIC SAC Commercial Aircraft Company (SACC), the aircraft manufacturer said on Wednesday.

Kent Fisher, Boeing Commercial Airplanes's vice president, described the work of the young SACC as "a tremendous accomplishment".

"SACC's ability to deliver these first panels on time and at our high standards for quality says a great deal about their capabilities and commitment to Boeing," Fisher said.

He regards advanced composites manufacturing as an area of critical importance as Boeing has increased production to meet market demand.

Forward torque box panels are an integral component of an airplane's empennage, providing rigidity to the stabilizers.

The finished panels will be shipped to Boeing's Composite Manufacturing Center in Washington state, where the 777 empennage is assembled.

Boeing qualified the SACC, a subsidiary of the Aviation Industry Corporation of China (AVIC), for composite work last year following a comprehensive audit of equipment, personnel and processes.

The SACC also supplies components for the 787 Dreamliner and 737 for Boeing, the largest buyer of aerospace components manufactured in China.
